Your not the only one its happened to. IVe had it happen but it was towards the end of the evening. Iwas getting ready to call it quits a little early cause i had plans so i get everything ready and im lowering my bow to the base of the tree when i hear this twing snap fairly close, and i look and there's a nice buck heading my way and he see's me had a starring contest for close to 10 min then he just turned around and headed back where he came from. its all part of hunting.....ya win some you lose some!!....this year has been more of a losing battle for me though
